[0038] The technical solution of the present utility model will be further described below in conjunction with the accompanying drawings and through specific embodiments.

[0039] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0040] Next, reference will be made to Figures 1 to 14 Describe a vibration damping bracket, a microphone, and a speaker according to an embodiment of the present utility model.

[0041] A vibration damping bracket according to an embodiment of the first aspect of the present utility model includes a lining sleeve 100, an outer lining sleeve 200, and a connecting arm 300; a mounting opening 110 is defined in the middle part of the lining sleeve 100, and the mounting opening 110 is used to accommodate the sound collector 500 of the microphone; the outer lining sleeve 200 is used to connect with the microphone body; the outer lining sleeve 200 is arranged around the lining sleeve 100 and is spaced from the lining sleeve 100; the connecting arm 300 is located between the outer lining sleeve 200 and the lining sleeve 100 and is connected to the outer lining sleeve 200 and the lining sleeve 100; the connecting arm 300 is inclined with respect to the central axis of the outer lining sleeve 200.

[0042] In an embodiment of the present utility model, the sound collector 500 of the microphone can be placed at the mounting opening 110 of the lining sleeve 100, and the outer lining sleeve 200 can be connected to the microphone body, so that the sound collector 500 can be fixedly installed in the microphone through the vibration damping bracket; when the microphone is vibrated in a direction perpendicular to the central axis of the outer lining sleeve 200 or parallel to the central axis of the outer lining sleeve 200, the vibration will first be transmitted to the outer lining sleeve 200 and then transmitted to the lining sleeve 100 via the connecting arm 300. Since the connecting arm 300 is inclined with respect to the central axis of the outer lining sleeve 200, it can reduce the difficulty of deformation of the connecting arm 300 when being vibrated in a direction perpendicular to the central axis of the outer lining sleeve 200 and a direction parallel to the central axis of the outer lining sleeve 200, so that the connecting arm 300 can be easily deformed when receiving the vibration from the outer lining sleeve 200, thereby making the vibration transmission efficiency of the connecting arm 300 relatively low, reducing the vibration amplitude transmitted from the outer lining sleeve 200 to the lining sleeve 100 via the connecting arm 300, thereby reducing the vibration amplitude received by the sound collector 500, achieving a vibration damping effect, reducing the noise generated by the sound collector 500 in the lining sleeve 100 due to the vibration of the outer lining sleeve 200, and improving the sound collection effect of the sound collector 500.

[0043] Specifically, when the shock-absorbing bracket is placed vertically, the central axis of the outer bushing 200 can be a vertical line formed by passing through the mounting opening 110, and when the shock-absorbing bracket is placed horizontally, the central axis of the outer bushing 200 can be a horizontal line formed by passing through the mounting opening. The connecting arms 300 are all inclined with respect to the vertical line and the horizontal line.

[0044] Specifically, the center of the cross-section of the outer bushing 200 is located at the central axis of the outer bushing 200. Among them, the outer bushing 200 is cylindrical, and the center of the cross-section of the outer bushing 200 is located at the central axis of the outer bushing 200.

[0045] Refer to Figure 1 、 Figure 2 、 Figure 11 and Figure 12 It can be understood that multiple connecting arms 300 are provided. The multiple connecting arms 300 are all connected to the outer bushing 200 and the inner bushing 100. By providing multiple connecting arms 300, the connection stability between the outer bushing 200 and the inner bushing 100 can be improved; the multiple connecting arms 300 are arranged at intervals around the central axis of the outer bushing 200, so that when the outer bushing 200 transmits vibration from any side to the connecting arms 300, the vibration can be transmitted to the inner bushing 100 through the multiple connecting arms 300, and the multiple connecting arms 300 are deformed to further reduce the vibration transmission efficiency and improve the shock-absorbing effect.

[0046] Specifically, the multiple connecting arms 300 are arranged at equal intervals around the central axis of the outer bushing 200 to ensure the stability of shock absorption.

[0047] Refer to Figure 1 、 Figure 2 、 Figure 11 and Figure 12 It can be understood that multiple connecting arms 300 are provided. The multiple connecting arms 300 are all connected to the outer bushing 200 and the inner bushing 100. By providing multiple connecting arms 300, the connection stability between the outer bushing 200 and the inner bushing 100 can be improved; the multiple connecting arms 300 are arranged at intervals along the central axis of the outer bushing 200, so that when the outer bushing 200 transmits vibration from any side to the connecting arms 300, the vibration can be transmitted to the inner bushing 100 through the multiple connecting arms 300, and the multiple connecting arms 300 are deformed to further reduce the vibration transmission efficiency and improve the shock-absorbing effect.

[0048] Specifically, the multiple connecting arms 300 are arranged at equal intervals along the central axis of the outer bushing 200 to ensure the stability of shock absorption.

[0049] In some embodiments of the present utility model, a plurality of connecting arms 300 can be arranged at intervals around the central axis of the outer bushing 200 and along the central axis of the outer bushing 200, so that the plurality of connecting arms 300 can be evenly arranged at intervals between the inner bushing 100 and the outer bushing 200, so as to further improve the stability of connection and the stability of vibration reduction.

[0050] Referring to Figure 3 and Figure 12 , it can be understood that along the axial direction of the central axis of the outer bushing 200, at least some of the connecting arms 300 are staggered, so as to facilitate the processing and demolding of the vibration damping bracket, reduce the processing difficulty, thereby reducing the processing cost, and the plurality of staggered connecting arms 300 can reduce the vibration transmission efficiency in the direction along the central axis of the outer bushing 200, so as to improve the vibration damping effect.

[0051] A plurality of connecting arms 300 can be arranged at intervals around the central axis of the outer bushing 200 and along the central axis of the outer bushing 200, and among them, the connecting arms 300 arranged at intervals along the central axis of the outer bushing 200 are all staggered.

[0052] Specifically, along the axial direction of the central axis of the outer bushing 200, the projections of the plurality of connecting arms 300 may partially overlap. For example, the projection of the connecting arm 300 located above along the axial direction of the central axis of the outer bushing 200 overlaps with the projection of the connecting arm 300 located below along the axial direction of the central axis of the outer bushing 200 by 1 / 3. Of course, according to the specific actual situation, the projections of the plurality of connecting arms 300 may not completely overlap.

[0053] Referring to Figure 2 and Figure 5 , it can be understood that the inclination angles between at least some of the connecting arms 300 and the central axis of the outer bushing 200 are not equal to each other, so that the vibration wave phases of the connecting arms 300 subjected to the vibration perpendicular to the central axis of the outer bushing 200 are different, and the vibrations can be offset to a certain extent, so as to improve the vibration damping effect.

[0054] Referring to Figure 5, the first normal line 301 of the upper connecting arm 300 and the second normal line 302 of the lower second connecting arm 300 face different directions. Among them, the first cross-section of the connecting arm 300 perpendicular to the first normal line 301 is coplanar with the length direction and width direction of the connecting arm 300, and the second cross-section of the connecting arm 300 perpendicular to the second normal line 302 is coplanar with the length direction and width direction of the connecting arm 300; the normal lines of at least one connecting arm 300 are inclined with respect to both the vertical line and the horizontal line. Of course, the first normal line 301 and the second normal line 302 can be inclined with respect to both the vertical line and the horizontal line. The first normal line 301 and the second normal line 302 can be neither parallel nor perpendicular to the central axis of the outer bushing 200; the normal lines of multiple connecting arms 300 arranged along the central axis of the outer bushing 200 face different directions, which can make the vibration wave phases of the connecting arms 300 subjected to vibrations perpendicular to the central axis of the outer bushing 200 different, and can cancel out the vibrations to a certain extent to improve the vibration damping effect.

[0055] Of course, referring to Figure 6 and Figure 7 , according to the specific actual situation, the normal lines of two adjacent connecting arms 300 located above and below can also be set parallel to reduce the difficulty of production and processing.

[0056] Referring to Figure 2 , Figure 6 and Figure 7 , it can be understood that multiple inner bushings 100 are provided, and the multiple inner bushings 100 are arranged at intervals along the axial direction of the central axis of the outer bushing 200, and the multiple connecting arms 300 are respectively connected to the outer bushing 200 and the multiple inner bushings 100.

[0057] The installation openings 110 of the inner bushing 100 are provided through along the central axis of the outer bushing 200, and the radio receiver 500 can pass through the installation openings 110 of the multiple inner bushings 100 to improve the connection stability, and by providing multiple inner bushings 100, the propagation efficiency of vibrations in the direction parallel to the central axis of the outer bushing 200 can be further reduced to improve the vibration damping effect.

[0058] Specifically, the central axes of the multiple inner bushings 100 are coaxially arranged, and moreover, the central axes of the multiple inner bushings 100 are coaxially arranged with the central axis of the outer bushing 200.

[0059] Referring to Figure 1 and Figure 11, it can be understood that the connecting arm 300 has a first end 310 and a second end 320 along a first direction. The first end 310 is connected to the outer bushing 200, and the second end 320 is connected to the inner bushing 100. The first direction is set in the same direction as the width direction of the connecting arm 300, and the second direction is set in the same direction as the length direction of the connecting arm 300, or the first direction is set in the same direction as the length direction of the connecting arm 300, and the second direction is set in the same direction as the width direction of the connecting arm 300. There is an included angle between the first direction and the axis direction of the central axis of the outer bushing 200, and / or there is an included angle between the second direction and the axis direction of the central axis of the outer bushing 200, so as to ensure that the connecting arm 300 is inclined relative to the central axis of the outer bushing 200.

[0060] Specifically, in the embodiment of the present invention, the first direction is set in the same direction as the width direction of the connecting arm 300, the second direction is set in the same direction as the length direction of the connecting arm 300, there is an included angle between the first direction and the axis direction of the central axis of the outer bushing 200, and there is an included angle between the second direction and the axis direction of the central axis of the outer bushing 200, so that the inclination degree of the connecting arm 300 is relatively large, which can further reduce the difficulty of deformation of the connecting arm 300 when vibrating in the direction perpendicular to the central axis of the outer bushing 200 and in the direction parallel to the central axis of the outer bushing 200, making it easier for the connecting arm 300 to be deformed by the vibration from the outer bushing 200, and further reducing the vibration transmission efficiency of the connecting arm 300.

[0061] Next, refer to Figures 1 to 14 Describe the microphone according to the embodiment of the second aspect of the present invention. The microphone includes a housing 400, the vibration damping bracket of the above first aspect embodiment, and a sound receiver 500. The housing 400 is provided with a receiving cavity 401. The vibration damping bracket is disposed in the receiving cavity 401, and the outer bushing 200 of the vibration damping bracket is connected to the housing 400. The sound receiver 500 is disposed at the mounting opening 110 of the inner bushing 100 of the vibration damping bracket, and the sound receiver 500 is spaced apart from the inner wall of the receiving cavity 401.

[0062] The sound receiver 500 is fixedly installed in the receiving cavity 401 of the housing 400 through the vibration damping bracket, and the sound receiver 500 is spaced apart from the inner wall of the receiving cavity 401, so as to avoid directly transmitting vibration to the sound receiver 500 when the housing 400 is vibrated.

[0063] By adopting the microphone according to the embodiment of the first aspect of the above-mentioned utility model, in the embodiment of the present utility model, in the embodiment of the present utility model, the sound receiver 500 of the microphone can be placed at the installation opening 110 of the inner lining sleeve 100, and the outer lining sleeve 200 can be connected to the microphone body, so that the sound receiver 500 can be fixedly installed in the microphone through the damping bracket; when the microphone is vibrated in a direction perpendicular to the central axis of the outer lining sleeve 200 or parallel to the central axis of the outer lining sleeve 200, the vibration will first be transmitted to the outer lining sleeve 200, and then transmitted to the inner lining sleeve 100 through the connecting arm 300. Since the connecting arm 300 is inclined with respect to the central axis of the outer lining sleeve 200, it can reduce the difficulty of deformation of the connecting arm 300 when vibrating in a direction perpendicular to the central axis of the outer lining sleeve 200 and a direction parallel to the central axis of the outer lining sleeve 200, so that the connecting arm 300 can be easily deformed when receiving the vibration from the outer lining sleeve 200, thereby making the vibration transmission efficiency of the connecting arm 300 relatively low, so as to reduce the vibration amplitude transmitted from the outer lining sleeve 200 to the inner lining sleeve 100 through the connecting arm 300, thereby reducing the vibration amplitude received by the sound receiver 500, so as to achieve a damping effect and reduce the noise generated by the sound receiver 500 in the inner lining sleeve 100 due to the vibration of the outer lining sleeve 200, and improve the sound receiving effect of the sound receiver 500.

[0064] Specifically, the microphone body can be the housing 400 of the microphone.

[0065] Referring to Figure 9 and Figure 10 , it can be understood that the housing 400 includes a housing body 410 and a fixing bracket 420. An accommodation cavity 401 is provided in the housing body 410; the fixing bracket 420 is arranged in the accommodation cavity 401 and is connected to the housing body 410 and the outer lining sleeve 200; the housing 400 fixes the position of the damping bracket through the fixing bracket 420, and realizes the soft connection between the fixing bracket and the sound receiver 500 through the inner lining sleeve 100 and the outer lining sleeve 200 of the damping bracket, so that the sound receiver 500 is in a suspended state, improving the damping effect.

[0066] Referring to Figure 11 and Figure 12 , it can be understood that an annular boss 210 is provided on the outer end face of the outer lining sleeve 200, the fixing bracket 420 is in a ring shape, and the annular boss 210 abuts against the top end of the fixing bracket 420.

[0067] The fixing bracket 420 is in a sleeve shape, and the damping bracket and the sound receiver 500 can penetrate into the fixing bracket 420 until the annular boss 210 provided on the outer end face of the outer lining sleeve 200 abuts against the top end of the fixing bracket 420 to define the position between the fixing bracket 420 and the damping bracket.

[0068] Referring to Figure 1 and Figure 9, it can be understood that the fixing bracket 420 includes a base body 430 and a connecting member 440. The base body 430 is connected to the outer shell 400 and the connecting member 440; the connecting member 440 is disposed between the inner bushing 100 and the outer bushing 200 and is connected to the outer bushing 200.

[0069] The base body 430 is fixedly connected to the housing 410 to improve the stability of the damping bracket within the housing 410; the connecting member 440 passes between the inner bushing 100 and the outer bushing 200 to prevent the housing 410 or other components within the housing 410 from colliding with the connecting member 440, increasing the vibration amplitude, and can prevent the vibration from being directly transmitted to the connecting member 440, and can reduce the space occupied between the fixing bracket 420 and the anti-vibration, so as to reduce the volume of the microphone.

[0070] Specifically, an installation groove 220 is provided at the side end of the outer bushing 200. The connecting member 440 includes a connecting piece 441. A limiting block 442 is provided on the outer side end of the connecting piece 441. The connecting piece 441 passes between the inner bushing 100 and the outer bushing 200, so that the limiting block 442 is embedded in the installation groove 220, and the connecting piece 441 abuts against the outer bushing 200 to define the position between the connecting member 440 and the outer bushing 200; wherein, at least two connecting pieces 441 are provided and are oppositely arranged, and the connecting piece 441 has elasticity to reduce the difficulty of connection and improve the stability of connection.

[0071] Of course, according to the specific actual situation, the limiting block 442 can be provided on the side of the outer bushing 200 facing the inner bushing 100, and a corresponding installation groove 220 is provided on the connecting piece 441; the outer bushing 200 is in a cylindrical shape, and the connecting piece 441 is in an arc shape.

[0072] Refer to Figures 1 to 14 , according to the speaker of the third aspect of the present invention, the speaker includes a box body 600, a first buffer layer 610, a second buffer layer 620 and the microphone of the second aspect of the embodiment; the box body 600 is provided with a receiving groove 601 for receiving the microphone; the microphone is disposed in the receiving groove 601; the first buffer layer 610 is disposed in the receiving groove 601 and is disposed around the circumference of the microphone and abuts against the outer shell 400 of the microphone; the second buffer layer 620 is disposed in the receiving groove 601 and abuts against the bottom of the outer shell 400 of the microphone.

[0073] The microphone is disposed in the receiving groove 601, and the outer shell 400 of the microphone abuts against the first buffer layer 610 and the second buffer layer 620.

[0074] The microphone can be placed in the accommodation groove 601 to accommodate the microphone. The first buffer layer 610 abuts against the peripheral wall on the outer side of the microphone to filter vibrations in the horizontal direction, while the second buffer layer 620 abuts against the bottom of the microphone to filter vibrations in the vertical direction. By providing the first buffer layer 610 and the second buffer layer 620, a vibration damping effect can be achieved for the microphone.

[0075] Referring to Figure 13 and Figure 14 , specifically, both the first buffer layer 610 and the second buffer layer 620 are elastic; on the side of the first buffer layer 610 close to the microphone, a plurality of first protrusions 611 are provided. The first protrusions 611 are arranged around the microphone and abut against the outer shell 400 of the microphone. When the box body 600 is vibrated, the vibration will be transmitted to the first buffer layer 610 and then to the microphone. By providing the first protrusions 611, deformation can occur when the microphone vibrates, so as to reduce the amplitude of the microphone vibration and achieve a vibration damping effect; among them, on the side of the first buffer layer 610 away from the microphone, a plurality of second protrusions 612 are provided. The second protrusions 612 abut against the inner wall of the accommodation cavity. The second protrusions 612 are arranged around the microphone. The second protrusions 612 can deform when the microphone vibrates, so as to reduce the amplitude of the microphone vibration and achieve a vibration damping effect.
